Abstract
Femtosecond time-resolved two photon photoemission has been used to investigate the dynamics of photoexcited electrons at a polycrystalline Al surface. The measured relaxation time data are very different from the behavior predicted for a Fermi liquid. We observed a distinct increase in the decay rate of the excited states. The origin of this strong deviation from the theoretical prediction may be transport effects or band structure effects induced by the periodic crystal lattice.
